HENRY M. GLOVER, OF GOLDTHWAITE, TEXAS.

HARROW.

To all whom it may concern Be it known that I, HENRY M. GLovnR, residingat Goldthwaite, in the county of Mills and State of Texas, have inventedcertain new and useful Improvements in Harrows, of which the followingis a specifi' one section will run on one side of the drillA and theother section on the other side of the drill plowing a full row attatime, it being of course understood that the cultivator blades are firstremoved in order to accommodate my invention.

Generically the invention resides in providing a simple frame of generaltriangular form on which the harrow teeth are horizontally andvertically adjustable so that they can be set at any desired positioniii a short space of time and with but little labor.

In its more subordinate nature, the invention includes those noveldetails of construction, combination and arrangement of parts, all ofwhich will be first fully described, and then be specifically pointedout in the appended claims, reference being had to the accompanyingdrawings, in which- Figure 1 is a perspective view showing one way ofapplying my invention. Fig. 2 is a perspective view of one of thecombination plow and barrow sections or units, the same being shownapplied on the foot of the cultivator. Fig. 8 is a cross section on theline 3 3 of Fig. 2. Fig. 4f is a detail perspective, parts being brokenaway showing a different adjustment of the teeth.

In the drawing, 1 represents the cultivator which may be of the ordinarytype, and to the foot 2 of which the combination plow and harrowsections are secured in any desired manner so as to lie one at each sideof the drill, the preferable manner of securing being shown in Fig. 2 ofwhich further description will be made. Each seotion includes a frame ofstrap-like metal consisting of the rear bar 5, the front cross bar 4,and the side bars 3, which side bars Specification of Letters Patent.

lie at acute angles to the rear bar 5 and are connected by said rear baras is clearly shown in Fig. 2. The bars 3 3 carry the reversible harrowteeth. The teeth 9 are adjustably clamped to the bars 3 by clampingplates 7 and bolts andnuts 8, and if found desired, the teeth 9 may beprovided with notches 11 to engage the bolts 8 for purposes ofadjustment. The lower end of each tooth 9 is bent at right angles as at12, with the upper portion of said tooth and extends under the bars 8 3,said bent over` part forming a toothed or penetrating end 10 of anydesired configuration, its purpose being to enter and plow the ground.By

reason of the quarter twisting of the teeth 9, as at 12, a resilient endis provided which is desirable in this class of tools for the kind ofwork it is intended for.

As before mentioned the attachment is fastened to the foot of thecultivator. This foot is usually provided with a slot 13 through whichthe cultivator blades are bolted, but on being removed to accommodate myimprovement, the slot is utilized for the reception of a bolt 14 and atongue 15 through which mediums the harrow is firmly and easilyattached.

The teeth as shown in Fig. 1 are used for plowing the ground but may bereversed as shown in Fig. t so that the device may be used as a harrowand for this reason the teeth 9 are sharpened or pointed, as at 16.

In practice for adjustment, the nuts and bolts 8 are loosened up and theteeth 9 with bars '7 are slid along the frame bars 3 to the desiredlocation, the teeth being raised or lowered as desired by changing theirpositions with relation to the bolts 8 and clamps 7.

From the foregoing description taken in connection with the accompanyingdrawing it is thought the complete construction, operation andadvantages of the invention will be apparent to those skilled in theart.

What I claim is 1. An attachment for cultivators, comprising atriangular frame formed of strap bar, a member' having a tongue securedin the front end of the frame, which tongue is adapted to enter the slotof a cultivator standard, and harrow teeth mounted on said frame.

2. The combination with a cultivator including a standard, the lower endof which is curved forwardly and longitudinally slotplace, together withbarrow teeth mounted ted, of a triangular frame of strap-bar, and onsaid frame. a tongue carrying member secured in the front apex end ofsaid frame to enter said standard slot, and a boli'l passing throughWitnesses: said frame, said tongue carrying member J. W. MASON, and saidstandard, for securing the same in l M. E. ARCHER.
